Well, I have taken it all apart and will be commenting on it in the next couple of days. I have already ordered parts to spiff it up.
What do you think of the stock unit for $99?
If I had DC problems like my customers do in some locales, it would be the first $99.00 I would spend to attack to problem. It is very nicely done. The ISO9001 facilities can and do some great work.
The casework extrusion is top notch as is the powder coating. I like the built in line tester, but that needs to be quieted down. Looks like a reasonable choice of parts and values given its' price. I'll be into it more as I go along. Almost wish I had (shhh, you know) on my AC lines to be able to tell. I'll have to build something to unbalance what I have and go about it that way, I think.
